Application filed May 7,1909. Serial No. 494,647.

To aZZ whom it may concern:

'Be it known that I, F RANK HANK, a subject of the German Emperor, and aresident of the city of New York, borough of Mam hattan, in the countyand State of New York, have invented a' new and Improved ResilientWheel, of which the followingis a full, clear, and exact description.

This invention relates to Vehicle wheels such as used on automobiles,carriages, or

similar vehicles. i

The object'of the-invention is to produce a wheel which will have greatresiliency and durability without embodying in its construction apneumatic tire. In its general construction the wheel comprises a diskor body of resilient material tion through the wheel taken on the line,

2-2 of Fig. 1.

Referring more particularly to the parts,

1 represents the body of the wheel which isin the form of an annulardisk formed of rubber or similar resilient material. In the centralopening of this body, the wheel center 2 is mounted. This centerconsists of a hub 3 which is adapted to receive the arm 4 of an axle 5,as indicated in Fig. 2. From the hub 3 spokes 6 radiate, and thesespokes are rigid with an inner rim 7, which rim is of channel form sothat it presents flanges 8' on each slde, as indicated in Fig. 2, and between these flanges the inner edge of the body 1 is received, as shown.The body is secured to the center by means of bolts or rivets 9 whichpass through the flanges 8,

as indicated most clearly in Fig. 2. The

wheel comprises also a rim 10 of light metal or snmlar material,present-mg a channel 11 on its outer side which receives a tire 12 ofSOllCl rubber or snmlar material. The run 10 has inwardly pro ect1ngflanges 13 at its sides, and between these flanges the outer edge of thedisk or body 1 is received. The rim is attached to the disk or body bythrough bolts .14 which pass through ,the flanges 13, as indicated.These bolts 14. also secure in position two spiders 15 which are placedon opposite sides of the wheel. Each of these spiders comprises an outerring 16, and these rings are disposed against the inner sides of theflanges and through them the bolts 14 pass, as indicated in Fig. -2.These spiders 15 have radially disposed arms 17 which extend in towardthe central axisof the wheel, and they project beyond the inner rim 7Their ends are all attached to two hub rings 18 which are arrangedrespectively on opposite sides of the wheel. These hub rings areconnected by heavy stud bolts 19 which pass through. the central openingof the wheel and maintain the inner rings a proper distance apart,asshown.

= As indicated in Fig. 2, the arms 17 preferably taper slightly towardtheir outer ends and their inner faces are provided with recesses 20 atthe location of the flanges 8.

The inner faces of these arms 17 are flat and lie close against the sidefaces of the body 1. They operate as stays or braces to prevent thelower portion of the wheel, which may tend to bein a state ofcompression, from bulging laterally. They also operate to hold the inneror central part of" the body in the same plane with the rim of the wheeland prevent the hub from shifting laterally out of this plane.

With a wheel constructed in this way a shock will be absorbed as thoughthe wheel were pneumatic, and thus reduce the amount [of power necessaryto drive the vehicle.

Having thus described my invention I claim as new and desire to secureby Letters Patent,-

A'wheel having an annular body of re silient material, in the form of adisk, an outer rim attached to the outer edge of the said body, a hubconcentric with said disk, and twoannular members concentric with saidhub, the outer of said members being attached to the inner edge of saidbody and having spokes connecting it With SiLid. hub, name to thisspecification in the presence of and the inner of said members havingraditwo subscribing Witnesses.

In testimony whereof I-have signed my PHILIP D. ROLLHAUS.
